57 BC. The fearsome Belgae have gathered a great army to oppose Rome, and Fronto and the legions assemble once more to take Caesar's war against the most dangerous tribes in the northern world. While the legions battle the Celts in the fiercest war of Caesar's career, the plots and conspiracies against him, both at Rome and among his own army, become ever deeper and more dangerous.

55 BC and Caesar's army gathers in the north of Gaul, preparing to drive away invading Germanic peoples and to traverse the dangerous northern ocean bringing punishment to the tribes of Britannia for their assistance of Gaulish rebels. But Fronto's troubles don't stop there. As his burgeoning relationship with Lucilia steps to a new level, so do his responsibilities at home, a situation exacerbated by the disruptive influence of the villainous Clodius in the city, causing trouble and endangering those about whom Fronto cares most.

As tensions build in Gaul and the druids manoeuvre the tribes towards general rebellion, Priscus and the diminishing senior staff of Caesar's army prepare to return to Britannia, this time with a vast army and a will to crush the tribes of that mysterious island. Meanwhile, Fronto contemplates a non-military future as he settles into the life of a married nobleman, socialising with Rome's elite and coming to terms with the decline in his fitness.  

It is the eve of destruction. Gaul seethes and bucks more than ever in revolt against the Roman invader, with even Caesar's allies beginning to question their loyalty. A conspiracy of Druids and Kings move the pieces into position in their great game of independence, all led by the powerful exile Vercingetorix. The lands of the Belgae burn in the vengeful aftermath of a winter that saw countless Romans butchered by the Eburone King: Ambiorix. 

It is 58 BC, and the mighty Tenth Legion, camped in Northern Italy, prepare for the arrival of the most notorious general in Roman history: Julius Caesar. Marcus Falerius Fronto, commander of the Tenth, is a career soldier and long-time companion of Caesar's. Despite his desire for the simplicity of the military life, he cannot help but be drawn into intrigue and politics as Caesar engineers a motive to invade the lands of Gaul.

It is 48 BC, and Caesar is master of Rome, but Pompey is at large in the huge recruiting grounds of the east with a core of powerful officers, nominally representing the senate in absentia. As the general deals with matters in the city, his army gathers at the coast, waiting to cross the sea and fight that worst of all conflicts: civil war.

After many months of clandestine organisation, Vercingetorix, backed by the druids and leading an army of rebellious tribes, is ready to make his first moves towards independence for his people and the annihilation of Rome's presence in Gaul. Meanwhile, Caesar tends to business in Aquileia, unaware that he is cut off from the bulk of his army in the north by the rebellion. Fronto and his friends are heading for a clash of armies the likes of which the north has never seen, and the Tenth's legate is about to face his most trying year yet.

51 BC. In the aftermath of the dreadful siege of Alesia, the tribes of Gaul lie broken and sparse, and yet the fires of rebellion still burn in the hearts of a few. As Caesar and his army continue to pacify the land wherever revolt can be found, a new conspiracy is rising. Lucterius of the Cadurci, survivor of Alesia, seeks to raise a new great revolt, building an army in his homeland, while a small group of dangerous warriors embark upon a secret and dangerous mission to rebuild all that was lost in that great siege.

 It is 50BC and Caesar winters with his legions in the north - all Gaul conquered but a triumphant return to Rome denied him by the senate who seek his blood. Yet unrest stirs in unknown lands, as the tribes of mountainous Aquitania rise under a terrifying new leader and drive out their Roman occupiers. Marcus Falerius Fronto, exiled from Rome, seeks out his former commander in an effort to build a future and soon finds himself in command of a most unusual legion with a remit to restore peace in Aquitania. 

The war in Gaul is over, but the fight for Rome is only just beginning. Denied his consulship by the senate and nearing the end of his term as governor, Caesar waits at Ravenna with one legion, making a last attempt at reconciliation. Threatened with prosecution if he returns to Rome, just one path is becoming clear: war against the senate. Fronto and Galronus are bound to the service of the Proconsul, facing a war against other Romans, and able neither to prevent nor avoid it. 

Promoted to the elite Praetorian Guard in the thick of battle, a young legionary is thrust into a seedy world of imperial politics and corruption. Tasked with uncovering a plot against the newly crowned Emperor Commodus, his mission takes him from the cold Danubian border all the way to the heart of Rome, the villa of the Emperor’s scheming sister, and the great Colosseum. What seems a straightforward, if terrifying, assignment soon descends into Machiavellian treachery and peril as everything in which young Rufinus trusts and believes is called into question....

After saving the Empire's richest province from a foreign army, Marcus and the men who protect him have been in hiding. Their lives will be forfeit if they are seen in Rome. But times have changed. Marcus's protector, the patrician legion commander Scaurus, has been summoned home by his mentor, a powerful senator who has decided he must act to save the empire from its debauched ruler's reign of terror. Rome is a hotbed of conspiracy and treachery and the senator is not the only contender for power. The emperor himself plans to destroy those he mistrusts, and no-one is safe.

As a boy, Alexander dreamed of matching the heroic feats of Achilles. At 18 he led the Macedonian cavalry to a stunning victory against the Greeks. By 25 he had crushed the Persians in three monumental battles and was the master of the greatest empire the world had ever seen. Men began to call him a god. But behind the legend was another, more complex story. 

As twilight descends on the third century AD, the Roman Empire is but a shadow of its former self. Decades of usurping emperors, splinter kingdoms and savage wars have left the people beleaguered, the armies weary and the future uncertain. And into this chaos Emperor Diocletian steps, reforming the succession to allow for not one emperor to rule the world, but four. Meanwhile, two boys share a chance meeting in the great city of Treverorum as Diocletian's dream is announced to the imperial court. 

1368. War is coming between France and Spain, and England, and in Italy the pope and the Visconti princes are battling for bloody supremacy. The worst years of Sir William Gold's life are about to begin. Leaving the side of his commander, Sir John Hawkwood, William embarks on a journey to serve the Count of Savoy, finding fame and favour in his service. But when his wife and children are struck down by the plague, William uses the poisoning of the Duke of Clarence as an excuse to escape on a witch hunt across Southern France and embark on a pilgrimage that he'd always pledged to do.
